Gutstring — Early Access Landing Page

My client Temi was launching a new platform called Gutstring and needed a clean landing page to collect early access signups before the official launch. The goal was simple - one page, one action. Users land on the page, click a button, enter their email and get confirmation. No distractions, no extra pages. The main challenge was the backend setup. The client wanted emails saved automatically and a thank you email sent instantly to every person who signed up, all without paying for any monthly tools or subscriptions. On the design side, the interaction needed to feel smooth and intentional. When a user clicks the Register Early button, it doesn't navigate to a new page - instead it animates and transforms directly into an email input field. Once they submit, the form fades out and a confirmation message appears on screen with a clean fade up animation. The whole experience feels seamless with no page refresh at any point. I solved the backend by building everything with Google Apps Script - completely free. When someone submits their email, it automatically saves to the client's Google Sheet and triggers a thank you email from their own email address. No Zapier, no Mailchimp, no extra costs. The result is a smooth, branded landing page with polished animations, instant success confirmation, and a fully automated backend that the client owns and controls entirely.
